This study was carried out to obtain informations on the variations of oil content and fatty acid composition among 90 Korean perilla collections. Average oil content of 90 perilla collections was 44.2% with a range from 29.7% to 61.9%. Perilla collections with late-maturing, super-large seed and gray seed coat showed higher oil content than other types in general. Average saturated fatty acid content in perilla oil was 9.0% with a range from 8.2% to 10.7%, while average unsaturated fatty acid content varied from 89.3% to 91.8% with a mean of 91.0%. Contents of saturated and unsaturated fatty acids were not related to maturity. There were no differences in the contents of saturated and unsaturated fatty acids according to maturity. Linoleic acid and linolenic acid contents were the highest in the super large-sized group(15.5%) and in the large-sized seed group(61.4%), respectively, while contents of fatty acids among the perilla collections were variable with different seed coat colors. Most of the traits studied were not significantly correlated with oil content, but linoleic acid($\omega$ 수식 이미지-6) content was negatively correlated (r=-0.217*) with linolenic acid(ω-3) content.

본 연구는 사육밀도에 따른 토종오리고기의 육질 특성을 비교 분석하기 위해 수행되었다. 사육밀도를 4, 5, 6, 7, 8 및 9수/㎡로 나누어 총 6처리구, 4반복으로 구성하였으며, 8주령 토종 실용오리(2.8±0.2 kg)의 가슴육(pH, 육색, 이화학적성상 분석)과 다리육(지방산 함량 분석)을 이용하였다. pH는 사육밀도가 높아짐에 따라 선형 및 2차 함수 형태로 감소하였다(P<0.05). 토종오리고기의 수분, 지방, 단백질 함량은 처리구 간에 유의차가 없었다. 회분의 함량은 사육밀도가 높아짐에 따라 선형으로 감소하였다(P<0.05). 육색(CIEL<SUP>*</SUP>, CIE a<SUP>*</SUP> 및 CIE b<SUP>*</SUP>)과 가열감량은 사육밀도가 높아짐에따라 선형으로 증가하였다(P<0.05). 전단력과 보수력은 처리구간 유의적인 차이를 보이지 않았다. Palmitic acid(C16:0)와 stearic acid(C18:0) 함량은 사육밀도가 높아짐에 따라 2차함수 형태로 감소하였다(P<0.05). Linoleic acid(C18:1n9)와 eicosenoic acid(C20:1n9) 함량은 사육밀도가 높아지면서 선형으로 증가하였다(P<0.05). γ-Linoleic acid(C18:3n6) 함량은 사육밀도가 높아짐에 따라 선형 및 2차 함수 형태로 증가하였으나(P<0.05), arachidonic acid(C20:4n6) 함량은 감소하였다(P<0.05). SFA와 TUFA는 처리구 사이에서 유의적인 차이를 보이지 않았으나, 사육밀도가 높아짐에 따라 MUFA는 선형으로 증가하였으며(P<0.05), PUFA는 선형으로 감소하였다(P<0.05). 본 연구의 결과들은 사육밀도가 토종오리에 미치는 영향에 대한 기초자료로 활용될 수 있다. This study was conducted to compare and analyze meat quality of Korean native duck (KND) meat relative to stocking density. The stocking densities under investigation were 4, 5, 6, 7, 8 and 9 birds/m². The experiment comprised six treatments and four replications, wherein the breast meat (pH, meat color, and physicochemical properties) and leg meat (fatty acid contents) of 8-week-old KNDs (2.8±0.2 kg) were used. pH of breast meat decreased linearly and quadratically (P<0.05) as stocking density increased. Ash content also decreased linearly (P<0.05) as stocking density increased; however, moisture, fat, and protein contents did not differ significantly among treatments. Furthermore, meat color and cooking loss (CL) increased linearly (P<0.05) as stocking density increased whereas neither shear force (SF) nor water holding capacity (WHC) displayed a significant difference among treatments. Palmitic acid (C16:0) and stearic acid (C18:0) contents decreased quadratically (P<0.05) as stocking density increased whereas, conversely, linoleic acid (C18:1n9) and eicosenoic acid (C20:1n9) contents increased linearly (P<0.05) as stocking density increased. Additionally, γ-linoleic acid (C18:3n6) content increased linearly and quadratically (P<0.05) as stocking density increased, but a decrease (P<0.05) was observed in arachidonic acid (C20:4n6) content. Saturated fatty acid (SFA) and total unsaturated fatty acid (TUFA) contents did not show significant differences among treatments relative to stocking density. However, monounsaturated fatty acid (MUFA) content increased linearly (P<0.05) and polyunsaturated fatty acid (PUFA) content decreased linearly (P<0.05) as stocking density increased. These results can be utilized as basic data for research on the effect of stocking density on KNDs.

유색미인 흑진주벼 등 5종, 일반미인 동진벼, 향미인 향남벼을 대상으로 이들 품종의 현미 중에 함유된 지방질의 함량과 지방질의 조성을 비교 연구하였다. 1. 총지방질 함량은 건물기준으로 2.04 - 4.68%로 Tohoku 149호, 한산흑미, 상해향혈라 순으로 많았고 흑남벼, 향남벼와 동진벼에서는 비교적 적었으며 그들간에는 차이가 없었다. 2. 총지방질의 조성은 sterol ester & hydrocarbon, triglyceride, free fatty acid, diglyceride, free sterol 등 5종이 동정되었다. 그중 triglyceride의 비율이 가장 높았고 그 다음으로 diglyceride 와 free sterol의 비율이 높았다. 일반미와 유색미 및 향미간에 비교했을때 triglyceride의 비율은 향미와 유색미가 일반미보다 낮은 반면 diglyceride의 비율은 향미와 유색미에서 일반미인 동진벼에 비해 월등히 높았다. 3. 총지방질 중 지방산 조성은 모든 품종 다같이 linoleic acid, oleic acid 및 palmitic acid가 주된 지방산이었고 linolenic, stearic acid은 소량이 함유되어 있었으며, erucic acid는 일반미인 동진벼에는 함유되어 있지 않았다. 양적으로 많은 지방산을 품종별로 비교해 보면 oleic acid는 한산흑미가 41%로 가장 많았고, 그외 품종은 32-37% 범위이었다. 또한 linoleic adid 향남벼와 상해향혈라는 각각 37%그외 품종은 32 - 36%의 범위이었다. The contents of total lipids and their components of brown rice grain were studied for 5 colored rice cultivars, 1 aromatic rice cultivar and 1 normal rice cultivar grown in Korea. The total lipid contents ranged 2.04 to 4.69% based on total dry weight. The Tohoku #149 showed the highest content which was followed by Hansanheukmi and Sanghaehyang-hyeolna. The lowest content were observed in three cultivars, Heuknambyeo, Hyangnambyo and Dongjinbyeo which showed no difference among cultivars. The main classes of the total lipid were triglyceride, diglyceride, free sterol, free fatty acid and sterol esters in all cultivars examined. The ratio of triglyceride in total lipid was high in colored rice and aromatic rice compared to Dongjinbyeo which is normal rice cultivars, but the ratio of diglyceride was high in Dongjinbyeo. The major fatty acid compositions in the cultivars examined were linoleic acid, oleic acid and palmitic acid. There was a varietal difference in fatty acid composition, for example, erucic acid was detected in aromatic and colored rices cultivars, while none of this compound was found in Dongjinbyeo.

We investigated the general composition, fatty acid composition and mineral content of ten kinds of marketed(3 domestic and 7 imported) mackerels. The moisture contents of domestic mackerels ranged from $62.9{\sim}67.8%$, and those of imported mackerels ranged from $61.1{\sim}74.7%$. Ash content was less than 2% in all mackerels. Crude protein content was greatest in Oman mackerel(24.1%) and lowest in UK mackerel(19.7%). Lipids contents ranged from 1.4%(Chile mackerel) to 19.7% (UK mackerel); mackerels with high lipid content tend to have low moisture content. Saturated fatty acids ranged from 18.2% to 31.1% of the total fatty acids content. The mackerel imported from Chile(26.8%) contained the least monoenes, while UK mackerel monoene content(48.7%) was highest. Polyenes were lowest in Tong-yeong mackerel(30.9%) and highest in Chile mackerel(50.0%). DHA content was highest in Chile mackerel(36.4%) and lowest in USA mackerel(14.6%). The mineral content of mackerels were in increasing order; K, Na, Mg, Ca, Fe, Zn and P. The K, Na, Mg and Ca content ranged from $261{\sim}420$, $261{\sim}420$, $37{\sim}176$, $34{\sim}49$ and $5{\sim}22mg/100g$, respectively.

The composition of fatty acids in bakery products from 35 bakeries in Seoul was analyzed by GCFID. The contents of crude fat in bakery products were represented 9.54-44.30% in pastries, 14.67-41.22% in cookies and 7.63-28.15% in whipped cream cakes. The total saturated fatty acid content in pastries, cookies and whipped cream cakes were 12.8-75.1%, 8.7-81.6% and 50.2-85.9% respectively. The proportion of trans fatty acids in pastries ranged from 0.00 to 3.37%. Cookies and whipped cream cakes were represented varying amount of trans fatty acid with highest value of 4.55% in cookies and 2.13% in whipped cream cakes. Total estimated daily intakes of fatty acids from pastries and whipped cream cakes were as follows : 1.2 g/day/person for saturated fatty acids and 0.014 g/day/person for trans fatty acids.

There are increasing interests in rearing edible insects in Africa, but information on how the feeds modify their fatty acids is largely lacking. In this work, the influence of artificial diets on the fatty acid contents and composition in the edible Ruspolia differens (Serville, 1838), in Uganda was assessed. R. differens was reared on the mixtures of six gradually diversified diets of two, three, four, six, eight and nine feeds. The diets were formulated from rice seed head, finger millet seed head, wheat bran, superfeed chicken egg booster, sorghum seed head, germinated finger millet, simsim cake, crushed dog biscuit pellet and shea butter. Fatty acid methyl esters were prepared using direct transesterification method, and analysed using gas chromatography. The contents of saturated, monounsaturated and polyunsaturated fatty acid differed significantly among the diets. The more diverse diets resulted in increased content of the polyunsaturated fatty acids. The n6:n3 ratio differed significantly among the diets and between the sexes, with R. differens fed on the four-feed diet having a higher n6:n3 ratio than those fed on other diets. Also, the fatty acid composition differed significantly among the diets, and diet diversification corresponded with the proportions of polyunsaturated fatty acids, especially linoleic acid. Overall, our results demonstrate that higher levels of essential fatty acids can be achieved by rearing R. differens on highly diversified diets. These findings are important in informing the design of future mass-rearing program for this edible insect.

In order to increase the industrial applicability of health functional materials using edible insects, effective extraction processes were explored to improve the quality characteristics of the free amino acids and fatty acids of Protaetia brevitarsis seulensis larvae (PBSL). After extracting PBSL under four conditions, water extraction at 50℃ (MWE), water extraction at 95℃ (HWE), ultrasonic extraction (USE), and high pressure extraction (HPE), the free amino acid content and fatty acid compositions of the extracts were evaluated. Essential free amino acid content as well as total free amino acid content were the highest in the HPE extract, followed by USE, HWE, and MWE extracts. In the HPE extract, the content of some essential amino acids increased dramatically, and the types of major amino acids had also changed. Additionally, the proportion of unsaturated fatty acids in PBSL was 69.9%, which was higher than the reported value in meat, the main protein source for Koreans. This level has also been further enhanced by USE (78.6%) and HPE (75%). These results show that HPE and USE can enhance the nutritive value of PBSL as a health functional material by improving the composition of free amino acids and fatty acids.

Jeong Bo-Young,Choi Byeong-Dae,Moon Soo-Kyung,Lee Jong-Soo The Korean Society of Fisheries and Aquatic Scienc 1998 Fisheries and Aquatic Sciences Vol.1 No.1

Fatty acid compositions of seventy-two species of Korean fish muscle, 59 species of sea water fish and 13 species of fresh water fish, were studied. Polyunsaturated fatty acid (PUFA) was the richest fatty acid group in all fish samples, accounting for $38.0\pm10.3\%$ of total fatty acids. Monounsaturated fatty acids $(MUFA,\;31.4\pm9.67\%)$ and saturated fatty acids $(SFA, 30.5\pm3.81\%)$ showed a similar level. There was a positive correlation between the total lipid content and MUFA (r=0.7788, p<0.001) and a negative correlation between the total lipid content and PUFA (r= -0.7786, p<0.001) while there was no correlation between the total lipid content and SFA. The proportion of n-3 PUFA and n-6 PUFA was $29.7\pm8.73\%$ and $6,48\pm3.70\%$, respectively, in all fish samples. The n-3 PUFA was rich in sea water fish while n-6 PUFA was rich in fresh water fish. The migratory fish contained the highest level of the n-3 PUFA $(1.82\pm1.01g/100g\;muscle)$, followed by the fresh water fish $(1.09\pm1.04g/100g\;muscle)$, the reef fish $(0.90\pm0.60g/100g\;muscle)$ and the demersal fish $(0.77\pm0.38g/100g\;muscle)$. There was a positive correlation between the total lipid and n-3 PUFA content, $y=0.2083\times+0.05 (r=0.9352,\;p<0.0010)$.
